In this paper we use the theory of semigroup of bounded linear operators in a com plex Banach space to establish the existence and uniqueness of a pseudo almost periodic mild solution of a retarded functional differential equation.
Pseudo almost periodic functions, almost periodic functions, exponentially stable evolution operator
